Method for controlling a material feed element

A method for controlling a material feed element in additive manufacturing of a layer or a body, wherein the body preferably has a plurality of layers, the method comprising:

• moving material in a direction of a material-dispensing nozzle through pressure applied by the material feed element as the material feed element covers a distance;
• determining the distance to be covered for building up the pressure by a desired material flow speed and by a previous actual material flow speed;
• multiplying the desired material flow speed by a factor;
• determining the factor by a difference between the desired material flow speed and the previous actual material flow speed;
• when a material flow speed changes, pilot-controlling a suitable compensation value gained from a mathematical product comprising the desired material flow speed and the factor;
• moving the nozzle at a track speed over a work table;
• reducing the pressure before an imminent reduction in the track speed, and increasing the pressure before an imminent increase in the track speed.
